MOBILE APP DEVELOPMENT

Mobile products hit walls that generalist developers can’t clear. Performance issues, platform-specific edge cases, apps that worked at 10,000 users and started cracking at 100,000. We’ve been building iOS and Android since both platforms launched. We know where the walls are.

What we can do for you

Build an app from scratch

Native iOS, native Android, or cross-platform — we scope the right approach for your product and build it end-to-end. Architecture, AI-driven development, testing, and App Store submission: we handle the full process so you don’t have to piece it together yourself.

Upgrade or rescue an existing app

If your app has hit a performance ceiling, accumulated technical debt, or needs new capabilities added without breaking what’s already working, we come in and fix it properly. We’ve taken over codebases in poor shape before. We know how to stabilize first, then improve.

Extend your mobile team

When your in-house team needs depth it doesn’t have — native iOS specialists, Android experts, reactive programming experience — we slot in. No months-long onboarding. No agency overhead.

Working with DECODE is a pleasure. Their expertise on iOS and Android is excellent and as well as working well with my team they’ve also presented workshops on mobile development to help train up my less experienced engineers.

Why us

There are many reasons we consistently provide clients with quality mobile apps.


Platform specialists, not generalists

We have dedicated iOS and Android teams. One developer “doing both” is not how we work. Platform depth shows in the product, especially when you hit the edge cases that only appear at scale.

1 team, 1 project

Your mobile team works exclusively on your product. No context switching, no divided attention. They learn your codebase deeply, and that knowledge stays with the team.

Fully in-house

Everyone works from the same office. Problem-solving is faster. Knowledge doesn’t get lost in handoffs between remote contractors across time zones.

Our collaboration models

Team-based

Access to a pool of seasoned experts.

Project-based

Building products regardless of scale.

NEXT STEPS

Before we start our partnership, we have to make sure
we’re a right fit for you.

Over a relaxed call or two, we’d like to hear as much as possible about your project
(fully NDA’d of course).

We’ll talk about:

  • Your expectations
  • Services you need
  • Your vision

There are a few steps in this phase:

  • We’ll hand-pick a team based on your desired seniority level and other requirements.
  • We’ll send you their CVs so you’ll know every engineer working for you.
  • If necessary, we can set up interviews between you and every engineer.

Only when you’re 100% on board with our choice, we’ll go to the next phase.

If everything sounds good to you, we’re ready to get started.

This could be the start of a great partnership

Don’t worry, any information you give us will only be stored for business purposes. Find out more in our Privacy Policy.
